[R] Formula variable help

2011-11-11 Thread rkevinburton 

I have an R script with the following applicable lines:

xshort - window(s, start=st, end=ed)
. . .
xshort - ts(xshort, frequency=1, start=1)
. . .
m1 - m2 - m3 - m4 - m5 - m6 - NULL
m1 - tslm(xshort ~ trend)

I get an error:

Error in get(dataname) : object 'xshort' not found

When I do traceback() I get:

3: get(dataname)
2: tslm(xshort ~ trend) at #19
1: model.cross.validation(l[[MEN]]$series)

Which points to the call to tslm above.  Since I am not supply 'data' to 
the tslm call (in the forecast package),, I am assuming that the code is 
dying here (in tslm):

 if (missing(data)) {
 dataname - as.character(formula)[2]
 x - get(dataname)
 data - data.frame(x)
 colnames(data) - dataname
 }

Any ideas what is failing?

Seems like it could work---can you save your script as a .txt file and
send it as an attachment, upload it online, or make a reproducible
example?

Cheers,

Josh

It seems that there is a bug in the forecast::tslm function. I have forwarded 
what I think is the bug (the call to get() should supply the argument 
'envir=parent.frame()').

Thank you.
